Aurora Borealis - FINLAND

The natural phenomenon known as "the Northern Lights" or Aurora Borealis always fascinated me and I have the dream of seeing them one day (of course that I feel the same for "the Southern Lights" or Aurora Australis but living in Europe it's easier to dream with Borealis than Australis)... I already have a card from Norway showing them, this one came from Finland and it's really beautiful (it appears to me that it is a photo composition and that the cabin was imposed on the sky,  but the result is very good). Thank you very much Krookus (lucky you that already saw the lights!). This postcard took 6 days to arrive!
  
Revontulet (Aurora Borealis) - FINLAND
     
An aurora is a natural light display in the sky particularly in the high latitude (Arctic and Antarctic) regions, caused by the collision of energetic charged particles with atoms in the high altitude atmosphere (thermosphere). Most aurorae occur in a band known as the auroral zone, which is typically 3° to 6° in latitudinal extent and at all local times or longitudes. In northern latitudes, the effect is known as the Aurora Borealis (or the northern lights), named after the Roman goddess of dawn, Aurora, and the Greek name for the north wind, Boreas.
